and now all i want to do is cry because everything -- we worked so hard, and we don't have a lot of money. >> reporter: governor murphy declaring a state of emergency. and, david, emergency workers tell me there was so much water, a river diverted and came barreling over the hillside. look at this debris. this is a highway here, and while emergency workers are trying to clear it out, the water continues pushing down this side street putting even more homes at risk of flooding. david. >> david: a summer of extremes. and we're only midway through it. trevor, thank you. the other part, the life-threatening heat wave, and authorities pointing to evidence of climate change again here in this country and across europe. in the u.s. more than 90 million americans in at least 15 states under heat alerts tonight. phoenix hitting 110 degrees for an 18th day in a row. and as i mentioned, the alarming water temperatures off florida tonight and what they're seeing in the coral. abc's victor oquendo out on the water tonight on this heat and the changing climate. >> reporter: tonight, this

record-breaking heat wave scorching millions across the country, around the world, and in the ocean, threatening lives and livelihoods. phoenix tying a record for 18 straight days of 110 degrees or higher. the air-conditioning failing at this apartment building. >> we can't even cook. we can't even do anything at home. as soon as you turn on the stove to cook, it turns to 95 degrees inside. >> reporter: overseas, parts of europe on fire, as that mediterranean heat wave intensifies. evacuations near the greek capital of athens as a wildfire rages out of control. this inferno in spain's canary islands destroying 10,000 acres forcing thousands from their homes. and here in the u.s., more evidence of the changing climate. the temperature in the waters off florida, normally in the 80s this time of year. now in the 90s threatening vital coral reefs. >> some of our long-term monitoring sites here off of miami are starting to show signs of early coral bleaching. >> reporter: over time,

excessively hot water can kill coral, causing those white spots. experts warn, this could be one of the most severe bleaching events ever with the peak of summer still to come. >> the florida keys literally would not exist if it were not for the coral reef tract. >> reporter: and the water temperature off miami beach, 95 degrees today. miami just hit a record, 37 consecutive days with a heat index of 100 degrees. david. >> david: really is extraordinary. victor oquendo tonight, victor, thank you. let's get right to chief meteorologist ginger zee tracking it all. and, of course, ginger, as i mentioned, it's only mid-july. we still have a long way to go this summer. >> reporter: that's the thing. it started so early, david, so now it's pick a record, any record on the map. let's focus on phoenix, not only this morning waking up for the eighth day in a row, which they've never done at 90 plus consecutively, but breaking that record of 110 plus, and there is no end in sight, somewhere like

el paso that has seen a consecutive 100 plus for 32 days, that smashes their old record, and it will keep smashing it day after day because we stay much above average through the end of the month. now i want to take you to the other part, the smoke. so, the wildfires have still been record-breaking up in canada. that smoke in the great lakes, the southeast tomorrow, settles upstate new york and vermont as well tomorrow evening. before we clear it out, there are storms. tonight it's about severe thunderstorm watches, lots of them, indianapolis, memphis to little rock. tomorrow night this part of the northeast where we are up to 300% of normal for the first two weeks of july, david, going to get more rain tomorrow evening. >> david: all right, ginger zee, we'll see you tomorrow. thank you. we move on to the other news and the chilling new clues after the arrest of a suspected serial killer, a new york architect and father accused of murdering at least three women. tonight, how many more cases could be there, and what they have now found in the suspect's home. here's our senior investigative reporter aaron katersky tonight. >> reporter: the painstaking search for clues in the gilgo beach serial killings is expanding tonight to every

crevice of the suspect's life, including two storage units along with the suburban long island home of rex heuermann, the architect and father charged with murdering three young women he allegedly solicited for sex and then killed. >> they're going inch by inch by inch through that house. >> reporter: in the basement, police now say they found more than 200 guns. dailymail.com capturing some of them. how concerning is that, that he had that kind of an arsenal? >> it was concerning and concerning enough where we didn't want to have the arrest at the house. we wanted to take him into custody somewhere outside of the house because of access to those weapons. >> reporter: neighbors and former classmates shocked. >> he was a weird guy. a very -- just a weird, strange, dark person. >> reporter: tonight, heuermann's lawyer said "there is nothing that would suggest he is involved in these incidents." heuermann has pleaded not guilty. prosecutors said the alleged killer contacted his victims using burner phones and later took their cell phones. investigators using phone

records to narrow the area where a potential suspect could be, then investigators looked for owners of a chevy avalanche, the vehicle an eyewitness linked to the suspect. prosecutors say eyewitnesses gave them a description of heuermann. >> he's a big guy. >> he was described as 6'4", 6'6", 250, 250 plus pounds and not like a muscle-bound person, but just a very large human being, and that's, you know, who he is. >> reporter: you used the word "ogre" in court. >> yeah, well, that was one of the witnesses that utilized that term, ogre, meaning a very thick, you know, thick-framed individual. >> reporter: prosecutors said dna from discarded pizza crust matched dna from a hair found on the burlap used to wrap the victims. amber costello, megan waterman and melissa barthelemy were discovered in december 2010, investigators locating their skeletal remains alongside ocean parkway. the women in their 20s, petite,

and sex workers, all found within a quarter mile of each other. the d.a. told us they're pulling a mountain of evidence out of this home here, david. it's all being swabbed for dna to see if there is a link to other gilgo beach victims, and, david, police all over the state are now looking through their cold case files to see if there might be a connection to this very same suspect. david. >> david: and you'll follow it for us. aaron katersky again tonight, thanks. now to the passenger in a small plane forced to take the controls after the pilot suffered a medical emergency during a flight from westchester county, new york, to martha's vineyard. the passenger, a 68-year-old woman, crash-landing the plane near the runway, and surviving with that pilot. here's janai norman tonight. >> reporter: tonight, a frightening and dangerous emergency landing, navigated by a passenger forced to take control of a small single-engine plane. >> single aircraft down, runway 6, one patient unresponsive at the time. >> reporter: the passenger, a

68-year-old woman from connecticut, was flying alone with a pilot saturday from westchester county, new york, to martha's vineyard. according to massachusetts state police, the 79-year-old pilot was on final approach to martha's vineyard airport when he suffered a medical emergency. the female passenger then, incredibly, jumping into action, taking the controls of the plane and crash landing just off the runway, coming to a stop on the plane's belly with no landing gear. the aircraft's left wing snapping in half. >> respond to the airport for an unknown medical. >> reporter: the pilot and passenger were both raced to the hospital as the airport was shut down for a time. tonight, the faa and national transportation safety board are both investigating the crash. and, david, massachusetts state police say that that pilot was later airlifted by medical helicopter to boston hospital in serious life-threatening condition. as for that passenger turned pilot, david, she remarkably suffered no major injuries. >> that's just incredible. janai norman tonight.

janai, thank you. we're going to turn to the war in ukraine and vladimir putin furious tonight after an attack on a key bridge that russia uses linking crimea to russia. what putin is now warning. our foreign correspondent james longman from inside ukraine again tonight. >> reporter: vladimir putin, tonight, vowing to respond after the latest attack on a vital bridge that connects russian-occupied crimea to the russian mainland. videos circulating online show the immediate aftermath. the kremlin claims ukraine used underwater drones to strike the kerch bridge. the claims are unverified, but the attack shut down traffic on this crucial supply route for russian forces. satellite images show a portion of it knocked out. russian officials say a couple driving on the bridge was killed, and their daughter seriously injured in the blast. the 12-mile kerch bridge is europe's longest and had been attacked last october in a massive truck explosion. it took months to repair, and putin made a point of driving across it after it was rebuilt. today's strike coming just hours

before russia said it was suspending the deal that allows ukraine to export millions of tons of grain through the black sea. russia claims international restrictions have hampered its own exports of food and fertilizer, and that it might consider resuming the safe-passage agreement only when its demands are met. experts say if ukrainian grain shipments are interrupted, it could lead to famine in some countries and rising food prices around the world. >> this is a deeply regrettable and, as i said, a dangerous decision that we urge mr. putin to reverse. >> reporter: david, the kremlin insists there is no connection between the suspension of the grain deal and the bridge attack. russian officials say repairs will take months. >> james longman in dnipro inside ukraine, james, thank you. >> david: back here in the u.s., tonight here the major shakeup for florida governor ron desantis and his staff and campaign team trailing donald trump by 30 points nationally,

even trailing in his home state of florida. rachel scott on the trail tonight. >> hello, south carolina! >> reporter: florida governor ron desantis, tonight, traveling to this key primary state, hoping to shake up his campaign and jump-start his stalled bid for the white house. desantis taking on republican front-runner donald trump with this pledge. >> yes, we will actually build the border wall, which we need. >> reporter: since he entered the race in may, desantis has followed further and further behind donald trump. he now trails the former president by about 30 points among republicans nationwide. he's even way behind among republicans in his home state of florida, and today that new headline, the governor's campaign is bleeding cash. he's raised about $20 million in the past six weeks, but already spent nearly $8 million of it, including $180,000 on private jets. the campaign now tightening purse strings, laying off about a dozen staffers. all the while, the florida governor under relentless attack from trump. >> desanctimonous and his establishment handlers are wasting such precious time and

resources to divide the party. they're dividing the party. >> reporter: desantis says reports of his struggles are off-base, insisting things will change once voters get to know him. >> when we're able to make that case to voters directly, we get a tremendous response, and so we're excited for the debates in august. >> reporter: but here in south carolina, republican voters like j.r. fountain aren't so sure. do you think desantis can beat trump? >> i don't know. i think he should. he's smarter, he's younger, and he's more vibrant, but trump's base, trump's loyalty is deep. >> reporter: at this point there does not appear to be any other republicans that will be jumping in the race. both new hampshire governor chris sununu and virginia governor glenn youngkin have ruled out a run for the white house, though youngkin appears to have wiggle room there. and as for the desantis campaign this is not the early lead they were hoping for and looking for a major reset in the coming weeks.
